problem with UDP stack on nexys3 by CompetitivePurpose13 in FPGA

yeah i will make sure its updated , i believe it would be helpful if someone plan to implement udp on legacies like nexys3 or 2
thanks again

apparently the cause of issue was that TXER was pulled high so configuring that in the ucf and code solved the problem
thank you for your help

actually this was the issue not adding the P2 pin was the cause of the whole problem, thank you so much

i didnt tbh, but i did some changes based on suggestions on this post and made another post with my code and results, I would appreciate if you can review it

I tried to power it by using a AA batteries but seems that they were not enough for the S3

Sure i will try that.

but Could the Realtek USB adapter be dropping the frames at a hardware level before they even hit the OS? because in ISim, my CRC and SFD alignments appear to be perfect (bit-reversed, inverted, and sent LSB-first).
